Improve moisture and nutrient retention!

This asbestos-free, odorless, horticulture-grade vermiculite provides superior moisture and nutrient retention when used as a substrate additive. It also allows for greater aeration, an essential component for larger flushes and faster colonization.

  • A3 medium coarseness is ideal for mushroom cultivation, as it has greater water retention capacity and can be used for external casings.
  • Ideal for use in cake-style, manure-based, and straw-based mushroom cultivation methods.
  • A thin layer can be added to the base of a fruiting chamber to increase ambient humidity.
  • OMRI Certified - product can be used in certified organic operations under the USDA National Organic Program.

⚠ CAUTION:

Avoid creating dust. Breathing dust may be harmful to your health. Use with adequate ventilation or with respiratory protection.
